Note: The hanging depth of the cutterhead center (mm) A and the distance between the cutterhead center and the rear wall (mm) B can be customized according to requirements.

The above technical parameters are for communication purposes only, and the final machine tool technical parameters shall be subject to the technical agreement.

The machining diameter of the workpiece is related to parameters such as the diameter of the cutterhead, the modulus of the workpiece, and the helix angle.

The SKXC-2000/16 is available with an optional rear column.

Process Matching

Rough milling

Large depth of cutting, suitable metal removal ratio, suitable for rough machining.

Semi Precision Milling

The use of semi precision milling cutter discs on precision milling machines can meet the requirements of efficient pre grinding processing, optimize processing efficiency, and overall cost.

Precision Milling

Using precision milling cutter discs on precision milling machines can achieve GB8 level accuracy.

Process Combination

Rough milling - Finish milling

The entire machining process of the workpiece can be completed by changing the tool on the same equipment, or it can be directly formed by using a precision milling cutter.

Gear Milling - Gear Grinding

For high-precision and high hardness workpieces, a semi precision milling cutter disc is used to leave a small normal margin for milling teeth and perform gear grinding and forming.

Message

Lathe Bed

Rectangular guide rail structure, good rigidity and vibration absorption.

Column

Double-layer ventral plate structure. The bottom is equipped with locking device to ensure the cutting rigidity. The back column mechanism is selected to realize the machining of gear shaft parts.

CNC System

The secondary development of human-machine interface(HMI) makes machine operation more convenient.

Semi and full protective structure

Available in semi-protected or fully protected construction.

Automatic rotation mechanism of spindle box

Meet the helical gear processing.

Spindle Box

Bilateral transmission, transmission of large cutting power and the use of active hydraulic anti-backlash structure, reduce the gear milling noise, improve the tooth surface finish.

Single/Double Worm Gear Turn/Rotary-Table

Adopting heavy-duty and high-precision turn-rotary-table. The locking device increases the cutting rigidity in the circumferential direction of the turn-rotary-table and suppresses radial and circumferential vibration of the turn-rotary-table.

Gear milling advantages

Scope of application

Efficient and high-precision machining of internal/external spur/helical gears, soft tooth surfaces, and hard tooth surfaces.

High Efficiency

Strong cutting ability of materials with hardness HB350.

Low Cost

Dry air cooling; Interchangeable blades with continuously improving lifespan.

Reliability

Adopting multiple advanced detection methods and cross sensing technology.

Customized Machining Path Planning

Can achieve specified tooth profile drum shape, K-shape, tilt, other given curves, symmetric/asymmetric tooth profile modification.
